Series 412/2 G1/2” is a 3-way solenoid valve with a balanced spool switching system and has two positions, normally closed, “3/2 N.C, The drive controI is electro-pneumatic type entrusted to the micro S.V. 15mm of the 300 series, while the repositioning is provided by a spring-return system.
Series 1000 (ISO 1, ISO 2, ISO 3) is 5-way solenoid valve with balanced spool switching system, and has two positions, “5/2”. The drive controI is electro-pneumatic type entrusted to the micro S.V. CNOMO of the 300 series, while the repositioning is provided by a spring-return system. It is also possible to operate the electro-operator by combining the electric drive with a monostable manual control.
IP Rating, “with connector installed” for both series is IP65.
The air necessary far the correct functioning of the electro-operator can be supplied in two different ways:
- Self-feeding (directly from the conducted supply of the valve)
- External-feding (indirectly from a conducted supply exterior to the valve)
The new feature in this version is the introduction of a diagnostic system able to monitor the ON/OFF state of the valve, with the possibility of increasing the reliability of the system with a double redundant channel configured on a base far the management of the pneumatic connections.
The state of the valve is constantly monitored by a diagnostic system realized using a Hall effect sensor “available in the standard version with a 2,5m, threewires cable” which reads the position of the spool and consequently the ON/OFF state.
- Sensor is in the ON position when the valve is at rest;
- Sensor is in the OFF position when the valve is activated
The SAFELINE supply and discharge valve in the single version is a classified component in CATEGORY 2 according to ISO EN 13849 and is appropriate for use in safety circuits until PL=C, while in the double version is a classified component in CATEGORY 4 according to ISO EN 13849 and is appropriate for use in safety circuits until PL=E.
